Fire dampers
Correct use FKR-EU

Design information
– Approved only for use in ventilation
and air conditioning systems
– If the fire damper is installed in solid walls
and ceiling slabs, timber stud walls as well
as shaft walls with a lower fire resistance class
than that of the fire damper, the fire resistance
class of the wall or ceiling slab applies
also to the FKR- EU
– Loads imposed on the casing may impair the
function of the fire damper. Install and connect
the damper in such a way that no loads
will be imposed on the installed damper.
– For particular applications it is recommended
that flexible connectors are used to connect
rigid ducting to the unit.
– Inspection accesses are provided
for maintenance and cleaning work
– For further information relevant to design,
in particular information on installation
situations, please refer to the operating
and installation manual.

Incorrect use
Never use the fire damper
– without specially approved attachments
in areas with potentially explosive atmospheres
– as a smoke control damper
– outdoors without sufficient protection
against the effects of weather
– in atmospheres where chemical reactions,
whether planned or unplanned, may cause
damage to the fire damper or lead to corrosion
If this fire damper is used in Germany:
– Do not use it as an air transfer damper.
– Do not use it in extract air systems
